Actual result: when the height of capsule is changing, the carve in the NavMesh is also changing.
Expected result: the NavMesh carve should not be related with the capsule height.

Note: the bug is happening when the NavMesh is with an particular "up direction" rotation (x axis = -90). If the NavMesh has rotation x axis = 90, then the carve is not related with the capsule height.

Reproduced with: 5.6.0b1, 5.6.0p2, 2017.1.0b1

Cannot be tested with 5.6 alpha and older versions because of NavMeshDataInstance class.
